This program is a small implementation of Conway's Game of Life with a twist: At first, the red cells are set to on or off, and they only affect the green cells. Then, vice versa, ad infinitum.
This library depends on the Lambency framework, which can be found here. Once
that repository is cloned, the rest of the steps are straightforward:
$ cd path/to/this/repo
$ cabal sandbox init
$ cabal install --only-dependencies
$ cabal install path/to/Lambency/repo
$ cabal configure
$ cabal run TwoPhaseCA
